Specification of Letters Patent. Patented July 16, 1912 Application filed June 2 0, 1911. Serial No. 634,215.

To all whom it may concern:

Be it known that I, THOMAS iVIOI N'IFORi), a citizen of the Dominion of Canada, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in J ewel- Settings, of which the following is a specification.

This invention relates to improvements in jewel settings and the objects of the invention are. to provide the inner surfaces of the setting and the sides of the cramps or cla\ with one kind of metal, whereas the main body of the setting made of another kind of metal which is exposed on the outer surfaces of the setting and claws.

To the accomplishment of the above objects, and to such others as may hereinafter appear, the invention comprises a setting, the main body and outer surfaces of which v are made of one metal, whereas the inner surfaces of the setting, which face the jewel held by the setting, are made of another metal usuallya metal which will better set off the jewel held by the setting.

Referring to the drawings: Figure 1 is a side view of a setting constructed in accordcramps B.

2 is a plan 2-) is a plan view of the surface blank. Fig. -t' is an end view of Fig. 2. Fig. 5 is an end View of Fig. 3. shown in Figs. 2 and 3 soldered together. Fig. 7 is a side view of the setting which has ance with my invention. Fig' been pressed from the assembled blanks shown in Fig. (3. Fig. 7. I

In .tlltifliltlWlllgS A designates the body blank which is made of one piece of metal suitably formed to provide claws or Fig. 8 is a plan view of designates the surface blank which is made of one piece of metal suitably formed asshown in Figs. 3 and 5 so as to inclose the body blank A leaving only the top surface of the blank A exposed-when the blanks A and t are assembled as clearly shown in Fig. ti. After the blanks A and (l have been assembled and suitably'soldered together to form a-single piece 'of metalfas shown in Fig. (3, the assembled blank is pressed into the form shown in Figs. 7 and 8, so that the surface blank C will cover the inner surfaces of the setting and the sides of the claws or cramps leaving the body blank cx- Fig. 6 is a plan view of the blanks posed on. the outer surface of the setting and the outer surface of the claws B as clearly shown in Figs. 7 and 8. In settings for holding diamonds and similar jewels, the luster of the jewel is greatly enhanced by the use of a suitable background and with this idea in views; great many settings are made entirely of platinum which is a white metal that: adds greatly to the brilliancyof the jewel. When the setting is made entirely of platinum it is not only very expensive but the outside.

of the setting, being white, is not nearly as" attractive as a gold setting. To overcome the above difficulties and at the same time to produce a setting which will notonly have all of the advantages of a solid-platinum setting and a solid gold setting, I have constructed a setting, made as above described, in which the body bla'nk A is made of gold and the surface blank (T is made of platinum. The surface blank C is made of rather thin platinum sheets as its only object isto cover the inner surfaces of the setting and the sides of the claws, the body blank A being made of sufficient thickness to afford the necessary strength.

\Vith a setting made, as above described,- of platinum and gold, it will be seen that a platinum surface is provided on all of the surfaces of the setting whiclrin any way 7 contribute to reflecting the light upon the. ewel, whereas a gold surface is provlded on all of the surfaces of the setting \VlllCll do not contribute to reflecting/the light upon the jewel. It is also to be noted that my improved setting is .cheaper than a setting made entirely of platinum with many more advantages- V \Vhile' the invention has been described with particular ref a'ence to the detail of constructitm, the sum is not to be considered as limited thereto, as many changes may be made and still fall within the scope of the following claims.

\Vhat I claim is z- 1. A jewel setting provided with claws, I

comprising a body blank of relatively thick metal, and a surface blank of relatively thinmetal, said surface blank being arranged to cover the inner surfaces of the-body blank and the sides of the claws of said body blank as aml for thepurposes set. forth.

2. jewel setting provided with claws, comprising a body blank of relatively thick metal, and a surface blank of relatively thin leaving" only one side of the body blank exmeta-l, said surface blank being arranged to posed, as and for the purposes setforth; inclose the body blank leaving only one side In testimony whereof I have signedthis of the body blank exposed, as and for the specification in the presence of two subscrib- 5 purposes setlforth. d d .h 1 ing witnesses.
